One must give tochacha unless he’s sure he’ll be ignored and the sinner will continue sinning.
Great! You both have had more than ample PROOF that your “tochacha” has been met with “continued sinning” (more of the same posts), by your own claims this has been the case. THEREFORE I expect, starting this VERY minute, that you both will put a STOP to your tochacha and cease from causing further sinning.
THANK YOU!
